I'm going to order my MBP in about 3 weeks, when it's offered in local stores. However I'm also finding it hard to decide is 5400rpm hd would be enough. My new MBP will mainly be used for working with sound AND graphics, which means managing large capacity WAV and PSD files should be as smooth as possible. I've been reading some articles about cases when 5400rpm hd sometimes might work faster than 7200 and I'm confused. Should I upgrade my future order to a 7200rpm hd, or is 5400 is going to fit my needs? P.S. Battery life and noise are much less meaningful for me, as long as the performance is at it's highest possible stage.
